Structuring
Process for creating microscopically structured surfaces and new surface properties.
During structuring, the material is melted in a controlled manner using a laser beam and solidified by the process control in such a way that a defined surface structure is created. Structuring can change the optical, mechanical, haptic or biological properties of the processed components. ACSYS laser centers work with pulsed lasers such as innovative Femtosecond Lasers for structuring.
Large field removal: paint removal on large and complex components
Seamless laser processing of components with an area of up to 1,250 mm × 1,250 mm in one piece with the highly developed Large Field Removal technology.
Laser ablation: material removal with laser technology
Laser ablation refers to the removal of material with the help of ultra-short pulsed laser radiation. The process is suitable for high-precision structuring and texturing of surfaces.
Optical structures for manufacturing tools
Laser technology can be used to create structures for injection molded parts, even in hard-to-reach places and with complex geometries. Typically, relatively small structural elements are inserted into a smooth and possibly polished surface. These structures, which are constantly, but not necessarily visibly, repeated, can be made up of geometric elements to create a certain visual impression, or of irregular structural units, such as those found in leather grain or a brushed wood structure.
Tilted contour lines as 2D structures for 3D effects
With tilted contour lines, realistic 3D effects can be created without depth engraving. This creates a three-dimensional effect with simple lines that are superimposed over the CAD relief and follow the height profile it contains – using pure 2D laser processing. The advantage is very fast process times combined with particularly high surface quality. The lines can be applied directly to the workpiece, but they can also be embossed or molded.
Rainbow structure as a safety feature
A rainbow effect is created when refractive structures in the nanometer range are introduced into the material using laser technology. As a kinegram or hologram, this effect can be used for high-quality applications such as the production of coins and medals, but also as a security feature for watches, jewelry, chip cards, ID cards, etc. The rainbow structure can be created directly and also embossed and impresses with its precise reproducibility.
Microstructuring
Microstructuring can be used to create complex 3D geometries and micro- and nanoscale structures on almost any surface. ACSYS uses Femtosecond lasers for this purpose. These allow a pulse duration of less than one picosecond. The heat input is so minimal that even sensitive materials such as plastics, glass, semiconductors or biological tissue can be provided with microstructures.
Surface functionalization
The surfaces of many workpieces can also be specifically functionalized using laser structuring. ACSYS laser systems, for example, use a process called Direct Laser Interference Patterning (DLIP). This creates interference patterns that can improve the adhesion of coatings, increase the corrosion resistance of materials or minimize surface friction.
Laser frosting
Laser frosting is primarily used for the production of polished molding tools such as dies for coin or medal production. It is the alternative of choice to classic frosting, in which a polished surface is partially masked and then sandblasted under a microscope. This is a very complex process, which the laser can perform much faster, more cost-effectively and more precisely.
Polishing / Finishing
With ACSYS Femtosecond Lasers and our patented Pulse Forging® technology, you can make surfaces clean, smooth and shiny – similar to polishing. Neither the material properties nor the hardness of the treated material are changed. In combination with Direct Laser Engraving, precise engravings with filigree gradients and finely polished surfaces are possible without changing tools. Pulse Forging® works more accurately than any other process and smoothes even the smallest structures with a surface accuracy of SA 0.1µm.
